Month view added

As requested by many users, we have upgraded the planning section of System One with a new user interface element. In addition to the familiar list view, a big month calendar has been added. Up to four events can be shown per day. If there are more items planned, these can be accessed by clicking the "more" link. Clicking on an event in the calendar will open a dialog with a summary. From there you can navigate to the detail view of the event.
